Loss of Syndecan-1 in Colorectal Cancer and Its Prognostic Implications
Author Information

Primary Institution: Cleveland Clinic
Hypothesis
Does the loss of epithelial syndecan-1 have prognostic significance in colorectal adenocarcinomas?
Conclusion
The study found that decreased syndecan-1 expression in colorectal adenocarcinomas correlates with higher TNM stage and local lymph node metastasis, but does not affect patient survival outcomes.
Supporting Evidence
- 87% of adenocarcinomas showed decreased or absent syndecan-1 expression.
- Decreased syndecan-1 correlated with higher TNM stage and lymph node metastasis.
- Reduced tumor syndecan-1 staining correlated with upregulation of stromal fascin.
Takeaway
In colorectal cancer, when a protein called syndecan-1 is missing, it often means the cancer is more advanced, but it doesn't change how long patients live.
Methodology
Immunohistochemistry was used to analyze syndecan-1 expression in a tissue microarray of colorectal adenocarcinomas and adenomas.
Limitations
The study did not find a correlation between syndecan-1 status and patient survival, which may limit its prognostic utility.
Participant Demographics
The study included 158 colorectal adenocarcinoma samples, with a mean clinical follow-up of 38 months.
Statistical Information
P-Value
p = 0.042 for gender correlation, p = 0.045 for TNM stage, p = 0.017 for lymph node metastasis
Statistical Significance
p<0.05
